B. Gear Experiments (Field)
B.1 NMFS, in collaboration with WWF, IATTC, and the WPRFMC Ecuador SEFSC John Watson
provided hooks, dehookers, and technical assistance to Ecuador SEFSC Charlie Bergmann
for the testing of non-offset 14/o and 15o circle hooks in the mahi PIFSC Chris Boggs
mahi fishery and 10 degree offset 16o and 18o circle hooks in the PIFSC Yonat Swimmer
tuna/shark fisheries. Work began in March 2004. Initial results
WESPAC Irene Kinan
indicate that the majority of the bycatch is entangled, not hooked.
Fewer turtles were caught on circle hooks, with varying degrees of
statistical significance, depending on the fishery and size of hook.
A report on the first year’s results is available.
B.2 As of June 28, 2004 Peru had retrofitted two vessels with 16o and Peru and Chile SEFSC Charlie Bergmann
18o circle hooks and is conducting work similar to Ecuador SWFSC Peter Dutton
above. Work has expanded in collaboration with the SWFSC and
PIFSC in 2005 to include more vessels. PIFSC Chris Boggs
B.3 1 Caribbean and 4 Gulf vessels will be testing an 18o, non offset Gulf/Caribbean SEFSC John Watson
circle hook vs the 16o circle hook typically used in the tuna
fishery, with standard squid/herring/sardine bait. Evaluations of
18/0 circle hook in the GOM tuna directed fishery have been
completed and a report has been submitted.
B.4 PIFSC staff are working cooperatively with the NGO PRETOMA Costa Rica PIFSC Yonat Swimmer
to test effects of offset on circle hooks and blue bait in the Costa
Rican tuna longline fishery.
B.5 PIFSC assisted with experimental design for blue dyed bait in the Costa Rica PIFSC Chris Boggs
shallow water mahi mahi fishery in Costa Rica. Initial testing in Brazil
Nov 2003 was unsuccessful, and work has shifted to hook testing.
B.6 Over the past 2 ½ years satellite tags have been provided to Costa Costa Rica PIFSC Yonat Swimmer
Rican longline observers to investigate post-hooking survival. A
total of 10 longline caught and 5 free-swimming turtles were
tagged and monitored, with no apparent behavioral differences
between the groups. With possible in the re-opened Hawaii
swordfish fishery, tagging in Costa Rica is being phased out.
B.7 In 2003 circle hooks were provided to approx. 10 swordfish Chile SWRO Peter Dutton
vessels. An 18o circle hook with 10 degree offset will be tested SWC
during the 2004 fishing year.
B.8 In the fall of 2004 University of Florida researchers tested an 18o Azores PIFSC Chris Boggs
10 degree offset circle hook baited with squid versus an 18o circle SEFSC John Watson
hook with no offset in the Azorean swordfish longline fishery. OPR Barbara Schroeder
B. 9 A cooperative research project between the Fisheries Research Atlantic and Gulf of SEFSC John Watson
Institute, NOAA Fisheries Service, College of William and Mary, Mexico
University of California, University of Miami, and Aquatic
Release Conservation was initiated in the Gulf of Mexico in April,
2005. The project is designed to investigate bycatch mitigation
techniques in the coastal longline fishery in the Gulf of Mexico
and Atlantic Ocean. The project will involve six cooperative
commercial vessels which will make 200 research sets using hook
timers and TDRs to investigate temporal and spatial relationships
between target and bycatch species and will test circle hooks and
baiting type and techniques to reduce mortality of bycatch species.
B. 10 SEFSC staff are working cooperatively with VIMS to provide Brazil SEFSC John Watson
circle hooks to Brazil for a billfish bycatch reduction research
B. 11 Monitoring of the reopened shallow set fishery in HI using 10 Hawaii PIFSC Chris Boggs
degree offset 18o hooks and fish bait indicated lower than
expected turtle bycatch rates. The ITS has not reached as the end
of 2005 approaches and target (swordfish) catch rates have been
consistent with before the gear change. This success in a different
fishery and ocean basin from where the gear was initially tested
should help to further expand the use of this gear.
B. 12 PIFSC is analyzing results from several vessels in the deep-set Hawaii PIFSC Marti McCracken
tuna fishery which is voluntarily trying small (14o–16o) circle
hooks with preliminary results indicating no significant
differences in target catches compared with vessels using tuna Dan Curran
hooks, but with little statistical power. Controlled (same vessel
18/o circle versus tuna hook comparison) testing of offset and
non-offset circle hooks is underway by 17 vessels in the tuna
fishery, in conjunction with action B. 13 below.
B. 13 PIFSC staff have been consulting with WESTPAC, Blue Ocean Pacific PIFSC Chris Boggs
Institute and Japan on a cooperative research design to test the
efficiency of small and large circle hooks in the Pacific longline
fishery. A draft research plan was reviewed in May 2004 and a
meeting to refine the draft was held in Honolulu, Sept. 13-17,
2004. Two hook testing research cruises were undertaken by the
National Research Institute of Far Seas Research of Japan in 2005,
while PIFSC initiated large (18o) circle testing in the Hawaii tuna
fleet (B.12 above).
B. 14 PIFSC is collaborating with Projeto TAMAR and IBAMA to test Brazil PIFSC Yonat Swimmer
18o circle hooks vs. 9o J hooks in commercial and research
vessels in the Brazilian swordfish fishery. A preliminary analysis
indicates reduced sea turtle bycatch, but also slightly reduced
swordfish catches with 18o hooks in this fishery.
B. 15 SEFSC staff held preliminary discussions with Korea and in July Korea PIFSC Chris Boggs
2005 Korean scientists met with PIFSC in HI to obtain circle
hooks and dehooking equipment for a research cruise completed
SEFSC John Watson
in the eastern Pacific in August 2005, where size 15o and 18o
circle hooks were compared with tuna hooks in deep-set fishing
for bigeye tuna. Preliminary results indicate some reduction of
target species CPUE with the larger hooks.
B. 16 Hawaii recreational shore fisherman are testing the removal of Hawaii PIFSC Bert Kikkawa
barbs from the circle hooks typically used in this fishery in an
experiment to determine if catch rates are maintained while
mitigating the live release of bycatch (mostly undersize or non-
target fish, as well as sea turtles). Preliminary results indicate
success which may by exportable to shore fisheries elsewhere.
B. 17 PIFSC provided a complete set of longline gangions, hooks and Philippines PIFSC Chris Boggs
spare gear to equip a research vessel operated by the Philippines
Dept. of Agr/Bureau of Fisheries and Aquatic Resources to
conduct comparison of longline fishing between tuna hooks and
16o circle hooks. A research cruise complete in March 2005
resulted in slightly reduced fish catch rates with the circle hooks
(not statistically significant) and PIFSC has received a proposal
for further work.
B. 18 PIFSC has agreed to supply some gear and instruments for a Mexico PIFSC Chris Boggs
continuing study of circle hooks versus J. hooks and tuna hooks
being conducted by government fisheries scientists in the Mexican
SWFSC Peter Dutton
B. 19 The Spanish Cetacean Society recently conducted tests substituting Spain PIFSC Chris Boggs
fish for squid bait in the Spanish swordfish fishery in the
Mediterranean Sea under contract from PIFSC. Preliminary
results indicated approximately a 50% reduction in loggerhead
bycatch with no reduction in target CPUE.
B. 20 The University of Naples has initiated a test comparing 16o circle Italy PIFSC Chris Boggs
hooks to J hooks in the swordfish fishery in the Pelagic Islands
(Mediterranean) under contract from PIFSC.
B. 21 In September 2005 based on turtle bycatch data from newly Indonesia and Papua New PIRO Ray Clarke
developed observer programs initiated by PIRO contractors in Guinea
those countries, PIRO and PIFSC contracted with WWF to
PIFSC Chris Boggs
develop and execute turtle bycatch reduction research in the
longline fisheries of Indonesia and Papua New Guinea.
B. 22 In January 2006 the SEFSC will meet with Costa Rica on Costa Rica SEFSC Charlie Bergmann
conducting baiting techniques research.
B. 23 In February 2006 the SEFSC in cooperation with the IATTC and Peru and Ecuador SEFSC Charlie Bergmann
PIFSC will begin work with longline fishers in Peru and Ecuador
to test a new circle hook design modification that effectively
PIFSC Chris Boggs
increases the width of the hook by using a wire appendage on the
back side of the eye. If effective this would allow smaller size
circle hooks in the Mahi Mahi fishery which has shown a
significant loss of catch with the standard circle hooks tested to
C. Possible Future Gear Experiments
C.1 An experiment on reducing entanglement in longlines is needed to Ecuador (Likely) PIFSC Chris Boggs
address this significant take component in many Latin American SEFSC Charlie Bergmann
fisheries. SEFSC and PIFSC are exploring options for testing
stiffer or deeper mainlines in the shallow set fishery in Ecuador or
C.2 Experiments with barbless circle hooks (see B. 16) will be Hawaii PIFSC Chris Boggs
expanded to the Hawaii longline fishery in 2006.
C.3 PIFSC is actively continuing to seek platforms throughout Asia Pacific PIFSC Yonat Swimmer
for the deployment of archival tags.
C.4 Guatemala has expressed an interest in experimenting with circle Guatemala PIFSC Chris Boggs
hooks in their swordfish fishery. The dorado and shark targeting
longline fishery will be supplied with non-offset 14/0 and 15/0
circle hooks for controlled comparison with other hook styles in
use, during a week long visit to Guatemala August 14-21, 2004.
C.5 At the FAO Technical Consultation a request was received from Uruguay SEFSC Charlie Bergmann
Uraguay for assistance in setting up experiments to evaluate circle
hooks. SEFSC staff will provide guidance and circle hooks for the
experiments. 18/0 circle hooks were provided to Uraguay in
January 2005 for evaluation on commercial vessels.
D. Gear Experiments (Laboratory)
D.1 Continued hook size experiments compared to turtle size were Galveston, TX SEFSC Sheryan Epperly
initiated in March 2004 with head started turtles in Galveston. PIFSC Chris Boggs
PIFSC is providing funds. Preliminary results were presented at SEFSC John Watson
